Question
White precipitate of silver chloride is soluble in :
Options
A.KCN solution (excess)
B.sodium thiosulphate solution (excess)
C.ammonia solution
D.concentrated solution of KCl
Solution
AgCl + 2CN- → [Ag(CN)2]- + Cl- ; AgCl + 2S2O32- → [Ag(S2O3)2]3- + Cl-.
AgCl + 2NH3 → [Ag(NH3)2]+ + Cl-.
AgCl is soluble in concentrated solution of KCl.
AgCl + Cl- → [AgCl2]- (soluble complex)
AgCl + 2NH3 → [Ag(NH3)2]+ + Cl-.
AgCl is soluble in concentrated solution of KCl.
AgCl + Cl- → [AgCl2]- (soluble complex)
